What is MiroFish?
MiroFish is an open-source, multi-agent AI simulation tool for scenario prediction. Instead of answering a question with a single guess, it builds a small synthetic world of AI agents, lets them react to your scenario over several rounds, and reports what emerged.
The project is public on GitHub, and the hosted version runs in your browser at mirofish.us — no install, no GPU, and no API keys required to try it.
How it is different from a chatbot
A chatbot gives you one confident opinion. MiroFish gives you a rehearsal: dozens of agents with their own personas argue, amplify, and change their minds, so you see how a reaction spreads rather than a flat summary of it. The output is a structured prediction report, not a single paragraph.
What you get back
Every run ends in a report with an executive summary, the risk signals the crowd surfaced, the narrative paths that formed, and follow-up questions worth asking. The generated world stays available afterwards, so you can keep interrogating it.
Is MiroFish free?
The source code is free and open on GitHub, and the hosted app lets you start without setup. Heavier runs on the hosted product may use paid credits.
Who is MiroFish for?
Marketers, product and policy teams, analysts, and researchers — anyone whose decision depends on how a crowd will react to an event.
